Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525930, here are decompositions:
- 3 + 31525927 = 31525930
- 11 + 31525919 = 31525930
- 17 + 31525913 = 31525930
- 41 + 31525889 = 31525930
- 89 + 31525841 = 31525930
- 113 + 31525817 = 31525930
- 131 + 31525799 = 31525930
- 167 + 31525763 = 31525930
Showing the first eight; more decompositions exist.
